device, pressing Enter after each. The default gateway can also be assigned,

if desired (press Enter to skip).

When finished, press Enter, then type reboot for changes to take effect. The

Saved Values and Current Values should now display both the changes made

(e.g., new IP address and subnet mask).

Creating Community Strings for SNMP

The purpose of community strings is to add a level of security to a network.

The default community string is named "public" and has read/write access.

Do not delete the community string “public” until the new community string

has been tested. Add necessary custom community strings such as one with

read/only access (for general use), the other with read/write access (for the

administrator).

To create a new community string, go to the main configuration screen and

press C. Enter the name of the new community (up to 16 characters, no

spaces) and press Enter. Then type one of the following to assign the

community string's access rights:

R = read-only access

W = read/write access

Enter = abort

Press Enter. When finished, press Enter, and type reboot for changes to take

effect. The Saved Values and Current Values should now both display the

changes made (e.g., new IP address and subnet mask). iConfig MIB

definitions allow the user greater control of Community Strings than serial or

telnet.

Deleting Community Strings

To delete all community strings (except the default, “public”) and start over,

press U. Press Y to delete all strings or N to abort. Then, press Enter. This

function will delete ALL community strings. To selectively delete community

strings, use iConfig.

Assigning Trap Destinations

A manageable device sends traps when a certain events take place. To enter

a trap destination, press T. Enter the IP address of the destination device

and press Enter. Then, type the name of the community string (that the

destination device has been configured to accept) and press Enter. This
